CRUDE-OIL BURNER.

SPECIFICATION forming part Of Letters Patent N0. 693,938, dated February 25, 1902.

Application filed September 23, 1901. Serial No. 76,268. (No model.)

To a/ZZ whom t may concern:

Beit known that I, GEORGE EMMETT WITT, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented a new and useful Crude-Oil Burner, of which the following is a specification.

My invention is an improved burner especially adapted for burning crude oil in steam or other furnaces; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is partly an elevation and partly a sectional view of a crude-oil burner embodying my improvements. Fig. 2 is a transverse sectional View of the same, taken on a plane indicated by the line a d of Fig. l. Fig. 3 is a similar View takenon a plane indicated by the line b b of Fig. l. Y

To an inlet-chamber l, which is here shown as a T-coupling, is coupled anoil-feed pipe 2, which is provided with a valve 3 to cut oft' or control the ilow of oil to the inlet-chamber. A steam-pipe 4, which leads from a boiler or other source of steam, is provided with an injector-nozzle 5, which enters and extends in the inlet-chamber through nearly the entire length of the latter and past the inner end of the oil-feed pipe 2. The said injectornozzle is of less diameter than the interior diameter of the inlet-chamber, so that a space is formed in the latter for oil around the injector-nozzle. The said steam-feed pipe -t is provided with a valve 6 to control the supply of steam to the burner. A mixing-chamber 7, which ishere shown as a perforated tube, leads from the inlet-chamber, the diameter of the said mixing-chamber being preferably less than that of Vthe inlet-chamber. The outer end of the mixing-chamber is here shown as closed by a plug 8, which is provided in its sides with channels 9. An atomizing jacket or chamber 10, which is here shown as a tube, surrounds the mixing-chamber and contains the latter, and the said tubular atomizingjacket is here shown as Icoupled directly to the-inlet-chamber. An -annular space is formed in the tubular atomi-Zing-jacket around the perforated tubular mixing-chamber. A jet-tip ll extends from the outer end of the atomizingjacket and is here shown as coupled thereto, as at 12. In practice the burner is disposed in or adapted to discharge into the furnace, and the latter heated by the steam. The oil-valve 3 is then opened to cause the oil to be fed to the inletchamber l. The oil strikes against the heated injector-nozzle and the interior of the inlet-chamber and is heated therein and thereby to such an extent as to cause itto iiow freely. The oil passes from the-inlet-chamber into the mixing jacket or chamber, where it is subjected to the action of the jet or blast of steam from the in jector-nozzle, the oil and steam becoming commingled in the mixingchamber 7, and the pressure and force of the steam causing the oil, which is commingled therewith, to be discharged through the perforations in the mixing-chamber into the atomizing chamber. The impact of the oil against the atomizing-chamber, together with the action of the steam, atomizes the oil, reducing it in the presence of the steam with which it is com'mingled to innitesimal globules, which, together with the steam, are discharged into the furnace through the jet-tip 11, the channels 9 of the plug 8 permitting the commingled steam and atomized oil to flow freely from the atomizing-jacket to the jet-tip. The said plug 8 centers the tubular mixing chamber in the atomizing jacket. The oil being thus atomized and comlningled with steam burns readily in the furnace withn out smoke and in a flame of great intensity. The action of the steam in passing through the parts of the burner keeps the latter clear, so that the .burner never becomes clogged with the oil and never requires to be cleaned. When the valves which regulate the admission of the oil'and steam to the burner have been once properly adjusted, the burner requires practically no further attention.

Having thus described my invention, I claim- 1. In a crude-oil burner, the combination of an inlet-chamber, an oil-feed pipe communicating therewith, a steam-pipe having an injector-nozzle extending into said inlet-chainber, a tubular perforated mixing-chamber leading.,r from the inlet-chamber, and an atomizing-chamber inciosing said mixing-chamber and into which the latter discharges, substantially as described.

2. In a crude-oil burner, the combination of an inlet-chamber, means to supply oil and steam thereto, a perforated mixing-chamber into which said inlet-chamber discharges, and an atomizing-chamber inclosing said mixingchamber, and into which thelatter discharges, substantially as described.

3. In a crude-oil burner, the combination the presence of two Witnesses.
